On non-displaceable Lagrangian tori on Fano toric surfaces: Wall-crossings and bulk-deformations | Posted on:2017-09-05 | Degree:Ph.D | Type:Dissertation | University:The University of Wisconsin - Madison | Candidate:Kim, Yoosik | Full Text:PDF | GTID:1450390005998569 | Subject:Mathematics | Abstract/Summary: | | We adapt Lagrangian Floer theory on the de Rham complex developed by Fukaya [Fuk] and Fukaya-Oh-Ohta-Ono [FOOOToric2] and [FOOOToric3] for a Lagrangian torus fibration possibly with singular torus fibers under some assumptions, focusing on deformations of the Floer theory by degree 2 cycles from an ambient symplectic manifold. As an application, we detect non-displaceable torus fibers of a Lagrangian torus fibration with a singular fiber on Fano toric surfaces constructed by Auroux [Auroux1]. We detect a continuum of non-displaceable Lagrangian tori on some Fano toric surfaces that are not related to any standard toric fibers by any symplectomorphisms. | Keywords/Search Tags: | Fano toric surfaces, Lagrangian, Non-displaceable | | Related items |
